I have a possibly quick question that I hope one of you can help with:

I am in need of making some relatively simple surface objects preferably in Moi3D and then I will need these objects to move in simple ways (simple rotation) relative to eachother with a couple of light sources shining down through parts of the objects. The objects should be variably transparent through their surface so that when they rotate the light sources shine through the surfaces to a varying degree. I hope it is just reasonably clear what I'm considering doing ;-)

One of you know if this can be done in a simple way with Moi3D? - or is there another program that is more obvious to use? If another program is more obvious it needs be intuitive and simple to use/learn to use and preferably a free-ware version as I basically only need to make this illustration.

If your model is simple enough you may be able to do the whole thing inside of of Simlab. If you need more detailed modeling, then MoI can be useful for creating the model and then you would export it out from MoI in OBJ format and then import that into Simlab for rendering and animation in there.

Thank you for giving me feedback on my question. Hmmm... Basically what I'm hoping to find is an "overall solution" to making these drawings that is as (relatively) simple and straightforward to use as I've found Moi3D to be.

I've previously looked at Blender but - to me - it was not as intuitive as I'd like it to be.

Sketchup might be an option, yet I'd rather use the time that it may take to learn sketchup to e.g. learn more of Moi3D.

And, since I only need one (or maybe a few drawings) I guess it's time to ponder what to do.
